This is a survey article about recent developments in semigroup C*-algebras. These C*-algebras generated by left regular representations of semigroups have been studied for some time, but it was only recently that several new connections and results were discovered, triggered by particularly interesting examples from number theory and group theory. We explain the construction of semigroup C*-algebras, introduce the basic underlying algebraic objects, define two important conditions called Toeplitz condition and independence, and present results concerning amenability and nuclearity, K-theory, and classification.
